Maybe I'm getting old but have become a bit tired of my dual out Monty muffler, while it has a nice deep growl, it's a bit loud and have my kids have to literally scream to talk to me when driving. Looking to either cap off one side or get a single out muffler. My question is, is there any performance differences between the two, more specifically later turbo spool up? Also, would I be better off selling the Monty instead of welding one side shut?? Thanks for any feedback. Bryce
